I'm currently a SAHM, heading back to work soon after having a few years off and two babies. My DH and I am just bought a house. Since we bought the house, SIL has been really unsupportive and makes snide comments about us, our parenting techniques and our new house. I know she's upset because she wanted to move to a bigger house but they couldn't afford it. She made a horrible comment about her friend a few years ago that she was a SAHM and they could afford a large house, like it wasn't fair that they could do this and she couldn't. I feel like she's upset that we bought this house but we've worked very hard over many years and made sacrifices to afford this house. We weren't rubbing it in her face. We didn't tell her how much we paid, she looked it up online. I'm so upset after every time I see her and I feel so sad about the whole thing. Should I avoid her even though my kids love to play with their cousins? Or AIBU?
